the experiment was conducted to determine α-amylase activity and the effect of seven plant species extracts including punica granatum l. (punicaceae), rheum officinale b. (polygonaceae), rhus coriaria l. (anacardiaceae), artemisia sieberi b. ( compositae), peganum harmala l. (nitrariaceae) , datura stramonium l. (solanaceae) and thymus vulgaris l. (lamiaceae) on α-amylase activity of four store...
Anthonomus grandis, the cotton boll weevil, causes severe cotton crop losses in North and South America. Here we demonstrate the presence of starch in the cotton pollen grains and young ovules that are the main A. grandis food source. We further demonstrate the presence of alpha-amylase activity, an essential enzyme of carbohydrate metabolism for many crop pests, in A. grandis midgut. Two alpha...
1. Rabbit antisera to purified rat parotid alpha-amylase were prepared. 2. The relationships between rat parotid-gland, pancreatic, serum and liver amylase were investigated by using the antisera in immunodiffusion, immunoelectrophoresis and immunoinhibition experiments. 3. Serum and liver amylase were identical, and very similar to parotid-gland amylase; pancreatic amylase was, however, quite ...
Alpha-amylase has a wide range of applications in starch industries, i.e. baking, brewing, distillery, etc. The alpha-amylase production from Streptomyces erumpens MTCC 7317 immobilized cells was compared with that of free cells. The immobilized cells of S. erumpens in calcium alginate beads were more effective for production of alpha-amylase (12.2% more yield) than free cells. Response surface...
Kidney beans, Phaseolus vulgaris, contain a proteinaceous inhibitor of alpha-amylase, which we have named phaseolamin. The inhibitor has been purified to homogeneity by conventional protein fractionation methods involving heat treatment, dialysis, and chromatography on DEAE-cellulose, Sephadex G-100, and CM-cellulose. Phaseolamin is specific for animal alpha-amylases, having no activity towards...
Inhibition of α-amylase is an important strategy to control post-prandial hyperglycemia. The present study on Ruellia tuberosa, known as traditional anti-diabetic agent, is being provided in silico study to identify compounds inhibiting α-amylase in rat and human. Compounds were explored from PubChem database. Molecular docking was studied using the autodock4. The interactions were further visu...
liquiritigenin is a chiral flavonoid present in plant based food, nutraceuticals, and traditional medicines. it is also an important ingredient present in licorice. the purpose of this study is to explore the pharmacological activity of racemic liquiritigenin utilizing several in vitro assays with relevant roles in colon cancer and diabetes. where possible, the pure enantiomers were tested to i...
Digestion of starch requires activities provided by 6 interactive small intestinal enzymes. Two of these are luminal endo-glucosidases named alpha-amylases. Four are exo-glucosidases bound to the luminal surface of enterocytes. These mucosal activities were identified as 4 different maltases. Two maltase activities were associated with sucrase-isomaltase. Two remaining maltases, lacking other i...
Diabetes is a chronic disease that occurs either when the pancreas does not produce enough insulin or when the body cannot effectively use the insulin. Natural alpha amylase and alpha glucosidase inhibitors from food-grade plants offer an attractive strategy to eather manage or prevent type 2 diabetes by controlling of starch breakdown and intestinal glucose absorption. Black tea is the second ...
